glenoid cavity

This cross-sectional descriptive purposive study was conducted among 150 (70 right and 80 left) fully ossified dry human scapulae of Bangladeshi people from January 2019 to December 2019 in the Department of Anatomy, Mymensingh Medical College, Mymensingh. Shape of the glenoid cavity was observed as pear, oval or inverted comma shape. Morphometric parameters such as length and breadth of glenoid cavity were measured by digital Vernier slide calipers. In this study, 19.13% cases were found inverted comma shaped, 35...

BACKGROUND: Neglected and locked anterior shoulder dislocation is a rare problem that presents several treatment challenges. Our study aimed to evaluate the functional outcomes and postoperative complications after open reduction and head preservation surgery in patients with neglected and locked anterior shoulder dislocation. METHODS: Ten patients (age 51 ± 22 years) with a follow-up of 27 months ± 7 months (range 24-40 months) were included in the study...

Scapular fractures are rare injuries that require different treatment strategies. Nondisplaced fractures and the majority of scapular body fractures can be treated conservatively, while surgical treatment should be considered for displaced fractures involving the glenoid. Displaced glenoid fractures of appropriate size and intra-articular step formation should be treated surgically. Different classification systems for scapular fractures can support the treatment decision. Postoperative and posttraumatic management should include early mobilization to achieve a good functional outcome...

The aim of this systematic review was to collect evidence on the following 10 technical aspects of glenoid baseplate fixation in reverse total shoulder arthroplasty (rTSA): screw insertion angles; screw orientation; screw quantity; screw length; screw type; baseplate tilt; baseplate position; baseplate version and rotation; baseplate design; and anatomical safe zones. Five literature libraries were searched for eligible clinical, cadaver, biomechanical, virtual planning, and finite element analysis studies...

Objective  This study assesses the relationship between the glenoid bone loss size and range of motion, functional outcomes, and complications in high-performance athletes undergoing bone block surgery for anterior shoulder instability. Methods  This retrospective study evaluated postoperative outcomes in athletes submitted to bone block surgery for anterior shoulder instability. In 5 years, 41 shoulders underwent the procedure; 20 had bone losses up to 15%, and 21 shoulders presented bone losses ranging from 15% and 25%...

OBJECTIVE: The glenopolar angle is a helpful criterion for recommending operative treatment. This study aims to determine the morphometric features of the scapula and provide essential information that supplies scapular biomechanics to produce a formula. METHODS: The study was carried out on 34 dry scapulae in the laboratory of the Anatomy Department of the Faculty of Medicine, Bursa Uludag University. We used calipers for the linear measurements and the ImageJ program for the area and angle parameters...

PURPOSE: Glenohumeral joint compatibility and bone morphology are among the most critical factors in shoulder stabilization. Our study investigated the effect of the bone morphological structure of the shoulder joint on anterior shoulder dislocation. METHODS: In our study, people with a history of shoulder dislocation were selected as the patient group. In the control group, patients with shoulder MRIs for any reason and no history of shoulder dislocation were included...

This study aimed to characterize three-dimensional quantitative morphological changes of glenoid fossa in patients with skeletal Class III malocclusion treated with bimaxillary orthognathic surgery. Ninety-five eligible patients (50 male, 45 female; mean age 22.09 years) were enrolled retrospectively. Cone beam computed tomography obtained at 1 week preoperatively (T0), immediately after surgery (T1), and at ≥ 12 months postoperatively (T2) were registered based on cranial base using voxel-based registration in 3D Slicer...

Background The inconsistent morphology of the scapula is based on variable dimensions of its glenoid cavity, in addition to its broadened and truncated lateral angle. Its variable shapes are attributed to the spinoglenoid cavity (superior and posterior aspect of the scapula), which appears oval, inverted comma-shaped, and piriform (pear-shaped). Traumatic conditions often lead to glenoid dislocation/fracture. The precise administration of total shoulder arthroplasty with glenoid component adjustment warrants a comprehensive knowledge of scapular morphology...

Locked shoulder dislocations account for up to 5% of shoulder dislocations. These relatively rare injuries are characterized by dislocation of the humeral head from the scapular glenoid cavity with the humeral head incarcerated on the glenoid in a "locked" fashion. Diagnosis is often delayed because of the complexity of clinical presentation and subtle radiographic findings, resulting in locking of the humeral head out of the glenoid cavity with severe functional deficits. Most commonly, there are bony injuries to the glenoid and humeral head that engage and prevent closed reduction...

Virtual surgical planning for CAD/CAM mandibular reconstruction by titanium prosthesis was recently reported for resected cases. Even if some advantages are evident, difficulties that may arise for TMJ function after reconstruction originate from prosthesis contamination through oral mucosa dehiscence. In these two cases reported of mandibular reconstruction after resection of ameloblastoma by custom-made CAD/CAM titanium prosthesis, the procedures were aimed to preserve the TMJ glenoid cavity and articular disc avoiding functional problems for hemi-mandibular resections that included the condyle (as in case #1) or with condylar preservation (as in case #2) and avoiding intraoral incisions in both cases...

Korean water deer (Hydropotes inermis argyropus; Heude, 1884) and Siberian roe deer (Capreolus pygargus; Pallas, 1771) are Korean wild deer classified in the tribe Capreolini. C. pygargus in Korea were previously considered a single species; however, it was recently suggested that roe deer living on Jeju Island (Jeju roe deer; Capreolus pygargus jejuensis) is a distinct subspecies from roe deer living on the Korean peninsula (mainland roe deer; Capreolus pygargus tianschanicus) based on several studies demonstrating genetic and morphological features...

Arthroscopic repair is the gold standard for treating Bankart lesions, with commonly used portals including the posterior, anterosuperior, and anteroinferior portals. The two anterior portals are established through a safe triangle created by the superior margin of the subscapularis, the inferior margin of the biceps tendon, and the anterior superior edge of the glenoid cavity. However, the disadvantage of this conventional method is that it can lead to crowding of the instruments at the rotator interval, making it difficult to handle...

Intracranial condylar dislocation to the middle fossa is rare, as it is not reported often. Known cases have an etiology, identified as erosion of the glenoid cavity from joint prostheses and/or traumatic events. As such, this case aims to offer a predisposing reason for the idiopathic condylar dislocation to the middle cranial fossa with nonfunctional limitations.

This technical note describes a method of diagnosing adhesive capsulitis of the shoulder based on the real-time study of abduction movement under fluoroscopy control after opacification of the joint cavity with contrast media. This movement passively or actively shows a limitation of the abduction, a scapulohumeral block, or a weak or even an absence of rolling of the humeral head in the glenoid cavity, transforming the abduction into a shoulder elevation.

BACKGROUND: Scapular surgery is usually undertaken via the posterior approach described by Judet. This approach allows access to the entire posterior scapular body; however, it results in severe soft-tissue injury and requires an incision in the deltoid muscle. To date, no clinical study has been reported on open reduction and internal fixation without capsular incision for displaced inferior glenoid fractures (Ideberg type II). The purpose of this study was to introduce an easy and less invasive approach to the inferior glenoid fossa and evaluate its clinical outcomes...

OBJECTIVES: A morphocline of the glenoid cavity has been used to infer differences in locomotor behaviors; however, the glenoid cavity is surrounded by the glenoid labrum, a fibrocartilaginous structure that could influence the functionality of the glenoid. The objectives of this study are to explore the effects of the glenoid labrum on the area, depth, and morphology of the glenoid cavity in primates. MATERIALS AND METHODS: Photogrammetry was used to build 3D models of the glenoid, with and without the labrum, and three- (3D) and two-dimensional (2D) geometric morphometrics (GM) was applied...

BACKGROUND: Massive rotator cuff tears are defined as irreparable when tendon-to-bone or tendon-to-tendon continuity with the adducted arm cannot be restored and severe muscle fatty infiltration is present. Tendon transfer is a palliative procedure that improves shoulder function and relieves pain. METHODS: We reviewed the records of patients aged <65 years, whose irreparable posterosuperior rotator cuff tears had been managed with teres major tendon transfer at our institution...
